This invention relates to an improved structure which may be broadly defined as a stock gate, the same having more particular reference to an especially constructed gate constituting a part of a stock enclosure, wherein the gate is designed for applying a germicidal and lubricating oil or preparation to the stock passing through the gate.

More specifically stated, the invention relates to an adjustably swingable mounted gate constructed for efficient application of lubrication material, wherein the gateis constructed to swing open in either direction, and to automatically discharge the lubricant from a reservoir or tank, when the gate is-open.

The particular structural features and advantages of this improved arrangement, will from the folbecome more readily apparent lowing description and drawings.

In the drawings Figure 1 is an elevational view of a lubrieating gate constructed in accordance with the present invention.

Fig. 2 1s a vertlcal sectional view taken approximately upon the planeof the line 2-2 of Fig. 1.

Fig. 3 is a details. V

Fig. 4 is a cross sectional detail view taken approximately upon the plane of the line 4-4 of Fig. 1

Fig. 5 is a cross section taken approximately on the plane of the line 55 of- Fig. 2, wherein the lubricant controlling valve is shown closed.

Fig. 6 is a view like Fig. 5, showing the valve open.

Fig. 7 is a details. 7 4 I 1 Referring now to the drawings by reference numerals, it will be seen that the ordinal '8 designates a fence or other enclosure equipped with a relatively large gate frame. This frame 9 constitutes what is to be distinperspective view of one of the perspective view of one of the 7 guished as an outer spring. Located in this,

and suitably supported in spaced relation thereon is an inner double frame 10, having a cross bar 11 adjacent the top and a suspension rod 12 just beneath it.

At the bottom of the inner frame, is a flat metal strap 18, whose intermediate portion 1 i The gate ispresseddownwardly as at 14. is composed of a plurality of individual parts capable of separate operation or simultaneous operation, as desired. I Y

'Attentionis first invited to a vertical centralized board 15 embraced by a metal reinforcing frame 16 andswingably mounted on the central portion of the rod'12. This is provided at its top with a valve operating cam17 which serves in a manner to be hereinafter described. Also near the bottom, it is formed with notches 18 providing clearance, in a manner to be hereinafter specified.

The central portionof theboard 15, on its opposite faces, is provided with hair, rope, or other absorbent or other lubricant applying means 19. This part of the gate is freely swingable atall times, and provides a restricted passage for small stock. Its lower end, as will be observed is movable through they arched portion 14- of the bar 13. In cidentally, this bar 13, functions primarily as a keeper. I V

Supported on opposite sides of the central swingable section of the gate, we find a series of pairs of elongated substantially U-shaped grip members 20, whose upper-ends are provided for movement on the rod 12. It is to be noted however, that the member vided with a retaining pin 21 at its whichextends down thru an opening as at 13, and is locked thereto by a release'pin 22.

Normally the sections are locked against 85 movement.

It is to be noted too, that they are provided near the bottom with registering openings 28,,

for receptionof the movable coupling pins (not shown). 1 The idea of this arrangement is to permit the size of'th'e opening to be adjusted to accommodate the existing circumstances. As stated, the central section is the only one which is normally freely swingable'. However by taking out the pins 21, of the two sections 20 on its intermediate opposite sides of the central section, and passing a hori- V zontal coupling pin through the opening 23 in these members as well as through the open ings 24, inthe part 16', it will be seen that all is pro bottom,

or" shown in Fig. 2.

three of these sections will then be coupled together to swing as a unit. 1

The remaining two outer sections are still stationary. It is possible however, that 1 they too be pinned to the other sections to move therewith, thus making the entire gate swingable back and forth.

A liquid lubricant or preparation tank or reservoir is supported on the bar 11, and provided with an automatically operable control valve. This valve embodies a guide tube 26, (see Fig. 2), whose upper end extends through an opening in the top bar of the frame 10, and whose lowerend extends through an opening in the bar being held in place by retaining nuts 27.

The flanged portion of the tube is provided with diametrically opposite slots 28 for discharge of the liquid. Located in this tube,

is a slidable plunger valve 29, whose upper portion is cylindrical in cross section, and whose lower portion is reduced and flattened in cross section, as indicatedat 30. The por tion 30 is brought up opposite the opening 28,

1;- and the lubricant in the tank is allowed to flow down through the tube onto the gate and upon the absorbent and applicator means 19.-

The head 31 on the lower end of the valve rides upon the operating cam 17 as clearly Attention is called to a square plate 32, (see Fig. 4;), fastened to the upper end of the valve 29. This is in sliding contact with an upstanding guide 83, fastened properly in placeby a channelshaped base portion 34;. The parts 33 and 34 are formed integral intoa single bracket, which is fastened over the top barof the inner frame 10 in an obvious manner.

The purpose of this arrangement, is to prevent turning of the valve 29 so that the restricted portion 30 will register properly with the diametrically opposite discharge slots or openings 28 in the tube 26.

It is obvious that with this arrangement,

'45 the gate is adjustable in order to acconnnodate stock of dilferentsizes. The method of adjustment of the sections is quite plain however from the preceding explanation. It is further obvious, that as the gate is swung in either direction when the stock walks therethrough, it acts upon the control valve in the liquid reservoir or container, thus allowing the liquid preparation to gravitate for application to the head and body of the animal.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the construction, operation, and features of the invention, after reading the description in connection with the drawings. Therefore, a

more lengthy description is regarded unnecessary.

Minor changes in shape, size and re- C3- arrangement ofparts coming within the field of invention claimed may be resorted to if desired.

Having thus described my invention, what I claim as new is 1. In a gate structure of the class described, a frame, a horizontal gate rod on the frame, a plurality of gate sections suspended from said rod, and means whereby said gate sections may be operated separately or together.

2. In agate structure of the class described, a stationary frame, a cross bar adjacent the top of the frame, a valved lubricant container-supported on thecross bar, a pivot rod supported on the frame below the cross bar, and a sectional adjustable gate suspended from said rod, one of the sections of the gate being provided with means for operating the valve in said container.

3. In a structure of the class described, a stationary frame, a cross rod on the frame, a gate embodying a plurality of sections including a centralized freely swingable cen tral section, and a plurality of side sections,

together with cooperating means between the lower ends of the side sections and said frame for permitting said side'sections to be retained against movement or disconnected and coupled to the central section for movement therewith.

4. In a structure of the class described, a stationary frame, a suspension rod on the frame, a sectional gate having a central section suspended from the center portion of the rod and freely swingable, a plurality of
